No she shouldn't because she cannot be redeemed. All she can do is serve her punishment and actually try and do good things for the people she hurt and even than it will never make up for genocide. Furthermore, doing good things doesn't erase having done bad things. If Scarlet Witch does good things for Mutantkind than she will have earned the right to be tolerated but she should never expect to be forgiven for genocide nor should she ever take up a moral high ground when it comes to Mutantkind considering that all the things she has done.
